Application of Boron Nitride Ceramic Tube
High Temperature Insulation
Boron nitride ceramic tubes have extremely low electrical conductivity even at high temperatures (resistant to 2000°C). They can be used as insulating support tubes for heating wires and thermocouples, and effectively prevent short circuits and metal corrosion.
Couramment utilisé dans : High voltage and high temperature insulating tubes and insulators
High temperature gasliquid transportation
BN tubes have good chemical stability and do not react with nitrogen, argon, hydrogen, or fluoride. They can be used to transport corrosive gases and liquids.
Couramment utilisé dans :Inert gas transportation, vacuum coating equipment, semiconductor production
Vacuum Metallurgy
BN tubes can be used as high-temperature crucible tubes and evaporation source support tubes, and are particularly suitable for metals such as aluminum, magnesium, and copper. BN does not react with these metals.
Couramment utilisé dans :High-purity metal and precious metal melting and evaporation
Semiconductor Electronic Devices
In ultra-high vacuum and high temperature environments, BN tubes can be used as hot zone isolation tubes, reaction gas delivery tubes or protection tubes to prevent reaction products from contaminating devices.
Couramment utilisé dans :Wafer manufacturing, compound semiconductor (GaAs, GaN) epitaxial growth, ion implantation equipment
Aérospatial
BN tubes can be used as heat flow channels or insulation sleeves in extreme environments such as the aerospace industry to ensure structural stability under high temperature and strong radiation conditions.
Couramment utilisé dans :High-temperature components of aerospace propulsion systems, high-temperature insulating tubes

FAQ
Why are boron nitride tubes suitable for high-temperature applications?
Boron nitride tubes offer high thermal conductivity, a relatively low coefficient of thermal expansion, and excellent thermal shock resistance, making them an ideal choice for certain high-temperature applications. Under appropriate inert gas protection, boron nitride ceramic tubes can operate at temperatures exceeding 3000°C.
Can boron nitride be customized for specific applications?
Yes, GORGEOUS can customize boron nitride to meet the needs of various applications. This includes length, diameter, and connector type (e.g., flat, square, threaded, etc.).
How should boron nitride tubes be stored?
Boron nitride should be stored in a clean, dry environment away from moisture and mechanical stress.
Are boron nitride tubes chemically reactive?
Boron nitride is chemically inert and not easily corroded by chemicals, making it suitable for use in corrosive environments.
